REVOLVING-SEAT DAVENPORT.

Specification of Letters Patent.

Application filed September 23, 1912. Serial No. 721,811.

To all whom it may concern:

Be it known that I, ROYAL R. MILLER, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Revolving- Seat Davenports; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

In revolving seat davenports as heretofore constructed some difliculty has been experienced in pivotally supporting the davenport seat upon the davenport frame in such manner as to insure ease of action in opening and closing the davenport, and also to afford such outward displacement of the davenport seat and the mattress frame supported thereon to permit the same to clear the back of the davenport or other portionsv of the frame. Furthermore, in such davenports heretofore the opening of the davenport to extend the mattress framehas resulted in the elevation of the mattress frame above the normal level of the seat when closed, and in many instances connection of the seat frame with the davenport frame has been so insecure that such structures have frequently proven unreliable and unsatisfactory.

The object of this invention is to so construct a revolving seat davenport that the bed or mattress frame thereof shall be supported when extended at substantially the same level as the davenport seat when the device is closed.

It is also an object of the invention to afford a construction whereby the operation of opening or extending the davenport acts to move the seat and the parts supported thereon outwardly to a suflicient extent to afford ample clearance from the back of the davenport.

It is an object of the invention to afford a construction wherein the pivotal connection between the davenport seat and the davenport frame is exceedingly strong and durable, and whereby the'davenport seat with the -mattress frame and, bedding supported thereon is firmly supported in the davenport seat wher' closed, and-whereby the inverted davenport'seat affords a very rigid support for the inner half of the mattress frame when the device is extended.

It is an object of the invention to afford interlocking cam and pivot plates arranged in pairs at each end of the seat frame and davenport frame, and so constructed as to .interlock at all times in either of the adjusted positions of the device, to afford a rigid support, and serving also as a cam to adjust the seat with the load supported thereon outwardly or inwardly of the frame, as the device is opened or closed.

It is an object of the invention to afford an exceedingly strong, simple and durable device of the class described, consisting of few parts, and those so related as to render the device simple and certain in operation, and not likely to get out of order.

The invention in a preferred form is illustrated in the drawings, and is hereinafter more fully described.

As shown in the drawings: Figure 1 is an end elevation of a device embodying my invention, with the end of the davenport frame removed. Fig. 2 is a similar view showing the device opened. Fig. 3 is a top plan View of the same. Fig.4lisabottom plan view of the mattress frame. Fig. 5 is in enlarged view in elevation of the cam and pivot plates, showing the same at normal position. Fig. 6 is a similar view illustrating the relative position of said plates when the seat has been rotated about forty-five degrees from the normal position, in opening. Fig. 7 is a similar view, illustrating the position the plates assume when the seat is revolved past center in opening. Fig. 8 is a similar View illustrating the position and mutual engagement of the plates when the davenport is fully opened. Fig. 9 is an enlarged end elevation of the inner cam and pivot plate, that is secured to the davenport seat. Fig. 10 is a similar view of the stationary cam and pivot plate, that is secured to the end of the davenport frame. Fig. 11 is an enlarged fragmentary View illustrating the means for elevating and supporting the inner mattress frame section upon the davenport seat when open. Fig. 12 is a section taken on line 1212 of Fig. 2 and illustrates a convenient locking mechanism adapted for use in connection with my invention. Fig. 18 is an enlarged section on line 13-43 of Fig. 2, but with the davenport in folded position.

Fig. 14 is an enlarged section on line l t-1 L of Fig. 12, but with the davenport in folded position. Fig. 15 is an enlarged inner face view illustrating the articulation of the mattress frame sections together on the middle section thereof, at one end of the same and with the brace rod omitted.

As shown in the drawings: 1 indicates the end frame members and 2 the back frame of a davenport having pivotally mounted therein a davenport seat 3, upon which is supported the sectional mattress frame foldable to contain the bedding therein, and revoluble with said seat in opening and in closing the davenport. As shown, the seat frame l-is constructedof structural metal, for example, of angle bar, to afford a rectangular frame having the flanges directed upwardly and the webs directed inwardly at the bottom of the frame, afforded thereby, and having a resilient mattress fabric 5 connected on said webs to support the upholstery of the seat, which fits into the seat frame thus formed andbeneath which may be rovided springs of anysuitable kind if desired. Extending from each front corner of said mattress frame is an angle bar leg 6, which extends to near the lower end of the front leg 7 of the davenport, and on which, substantially filling the space-between the front leg 7 and the davenport frame, is a front or cover board 8 affording the front finish and con cealing the mattress frame and bedding when the davenport is closed, as shown in Fig. 1. Extending downwardly from the seat frame from the rear side thereof near each corner are short angle bar hangers 9, and secured within and between the hangers 9 and front legs 6 of the seat frame is a sub-frame 10, also constructed of angle bar, parallel with the seat frame and spaced slightly below the same. vR-igidly secured on the end at the outer side of the sub-frame near the middle thereof is a cam and pivot plate 11, said cam and pivot plate 11 is riveted along its upper edge to the end member of the subframe, as shown in Fig. 1, and projects well below the same. Secured in said cam and pivot plate near the rear end and on the inner side thereof is a cylindric pin 12 having an enlarged head 13 thereon, and, as shown, at its forward end said cam and pivot plate is extended to near the front edge of the davenport seat and is there provided with a downwardly facing shoulder 14: which lies substantially in alinement with the middle of said plate. As shown also a slot A is provided in said cam and pivot plate, which extends from near the pivot pin 12 horizontally and forwardly to near the middle of said plate, and then is directed downwardly to near the lower edge of the plate, as shown more plainly in Figs. 1, and 5 to 8 inclusive. An intersecting slot com municates in the slot A near the rear end thereof, and inclines upwardly and forwardly to near the upper edge of said plate, and above the downwardly directed portion of said slot A and at its extremity is directed slightly forwardly to afford a rear forwardly directed shoulder or detent 15 projecting thereinto. Rigidly secured upon each end 1 of the davenport frame, to correspond in position with the pivot and cam plate 11 on the sub-frame 10 is a locking plate 16 which is provided with a straight horizontal slot 13 extending longitudinally therein near its middle and from near the rear end of saidplate to near the front end thereof, and,

as shown, the upper wall of which is cut away near the middle to afford a short interval of greater width in said slot. The pivot pin 12 on the pivot and cam plate 11 extends into and its in said slot with the head 13 thereof lying outside the same and in a suitable recess or groovein the end frame to permit free travel of said pin in said slot, as shown in Figs. 5 to 8 inclusive and in Fig. 13. A pin 17 is rigidly secured on the inner side of said locking plate at a point therein to extend into the upper end of the inclined slot in said plate when the pivot pin 12 is at the rear end of the slot B in said locking plate, as shown in Fig. 5. As shown also an upwardly directed, inwardly sprung tongue 18 is provided integral with the forward end of the locking plate at a point to afford at its bottom a shoulder 19 to receive the shoulder 14- of the pivot and cam plate when the seat of the davenport is supported. in normal position, as indicated in Figs. 1, 5 and 13. Rigidly secured on the rear side of .the sub-frame at each corner thereof is a rearwardly and downwardly projecting bracket arm 20, and connecting the same and journaled at its ends in said brackets is a downwardly bent or sprung bar 21 which may be tubular if desired, and which is substantially straight for the greater part of its 1 length, the ends only bending upwardly and then outwardly to engage said brackets, and being of a suflicient length to carry the major portion of said bar downwardly to, and, if preferred, into the scat frame as shown in Fig. 2. Journaled on the ends of said brace bar adjacent each of said brackets 20. by means of a suitable aperturcd leg 22 ex tending downwardly on the under side thereof from near its middle is a short mattress frame section 23 constructed of angle bar. Articulated with the ends of said short mattress frame section 23 are the end rails 24; of the inner mattress frame section which, together with the inner side rails thereof,

are also constructed of angle bar rigidly engaged together atthe angles. An outer folding mattress frame section constructed similarly with the inner mattress frame section is articulated at the ends of its end members 26, with the outer ends of said short sections.

A short folding leg 27 is pivotally engaged at the outer side ofeach of the end frame members 24 of the inner mattress frame section, with the upper end thereof extending somewhat above the mattress frame, and of a length below its pivot on the mattress frame to bear upon the subframe as shown in Fig. 11 to support the inner mattress frame section at operative position when the davenport is extended. A bar 28 is pivotally connected with the upper end of said leg 27 and with the short section 23 of the mattress frame, as shown in Fig. 11, so that in opening and closing the davenport said leg is automatically extended to or retracted from supporting position. In a similar manner a leg 29 is pivotally engaged at each end of the outer or folding mattress frame section, and extends above the same, and is of a length to support the same in normal operative position and a bar 30 similar to the bar 28 is engaged on the short section 23 of the mattress frame and with the upper end of said leg to swing the same automatically as above described in opening or closing the davenport.

The operation is as follows: When the davenport is closed, as shown in Fig. 1, the mattress frame is folded beneath and supported on the seat, and the pivot cam plate and the locking plate are in mutual engagement, as shown in Fig. 5, that is to say, the pivot pin 12 is at the extreme rear end of the slot B in the locking plate and the shoulder 14 of the pivot cam plate bears upon the shoulder 19 of the locking plate. $aid cam and pivot plate is thus firmly engaged and supported on the locking plate and between said plate and the tongue 18. In this position the seat is in normal position and the pin 17 projecting into the inclined slot in the plate 11 is firmly engaged by the detent 15 in said slot, with any forward movement of the seat. When the seat is inverted as shown in Fig. 2 the pivot cam plate and the locking plate are in the relation indicated in Fig. 8, and a lock is provided to prevent the downward swing of the middle of the mattress frame by the weight applied thereon. Said lock rigidly engages the inverted seat from movement when the davenport is open, thereby maintaining the mattress frame in a horizontal plane. For this purpose a bolt 32 is slidably engaged through the flange on each of the front seat legs or brackets 6, and adapted to project into a suitable recess therefor in a plate 31 secured on the end of the davenport frame at the inner side thereof. Said bolt may be actuated in any suitable manner. As shown however a bell crank 33 is pivotally supported on the front board 8 at the inner side thereof, and one arm of the bell crank pivotally engages the inner end of the bolt and the other end thereof is adapted for manual engagement for actuation as shown in Fig. 12.

In opening the davenport the seat is rotated upwardly and inwardly, pivoting or rotating upon the pivot pin 12, the pin 17 serving as a fulcrum to move the pivot pin along the slot B in the locking plate as indicated in Figs. 6 and 7, and eventually entering the downwardly curved portion of the slot A, as shown in Fig. 7 and thereby moving the seat somewhat forward until the pivot pin is at the forward end of the slot B and the pin 17 is at the inner end of said curved slot. I'Vhen inverted the upper or folding section of the mattress frame may be engaged and sprung outwardly and downwardly, utilizing the short section 23 of the mattress frame as a lever to elevate the inner section, while the relative movements of the mattress frame section actuate said legs 27 and 29 through the connections afforded by the links or bars 28 and 30.

From the construction described it is obvious that an effective lock for the seat is afforded in each of its adjusted positions and that a relatively large space is afforded for bedding within the folded mattress frame when the device is closed. Of course the mattress frame may be provided with any desired number of folding sections, dependent upon whether a. long or a short davenport frame be employed, and if desired other or supplemental locks may be employed.

In the construction illustrated in Fig. 4, I have shown a wood frame comprising end members 34 and a back member 35 and the front board 8, which are secured to inclose the seat frame and to which the upholstery may be tacked or otherwise secured if preferred.

Details of the construction may of course be varied. I have shown a preferred form of my invention, and I do not propose limiting the patent therefor otherwise than as necessitated by the prior art.
